Answer:
The variable of interest is the proportion of flips that land the correct way when flipped randomly.
The necessary conditions and
are present.
The 98% confidence interval for the overall proportion of bottles that land correctly when flipped randomly is (0.131, 0.167).
Step-by-step explanation:
Variable of Interest:
Proportion of flips that land the correct way when flipped randomly.
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
Necessary conditions:
The necessary conditions are:
You observe 2180 random, independent flips, and 325 land the correct way.
This means that
Necessary conditions
The necessary conditions and
are present.
98% confidence level
So , z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:
The upper limit of this interval is:
The 98% confidence interval for the overall proportion of bottles that land correctly when flipped randomly is (0.131, 0.167).
Answer:
It will take him <u>20 days</u> to read a 300-page book.
Step-by-step explanation:
Given:
Stephen read a 90-page book in 6 days.
If he continues reading at that rate.
Now, to find the time it will take him to read a 300-page book.
So, we solve using unitary method:
If, Stephen read 90 pages in 6 days.
So, Stephen read 1 page in = days.
Thus, Stephen read 300 page in =
Therefore, it will take him 20 days to read a 300-page book.
